AMD Ryzen 5 7600X users may want to avoid updating to the new AGESA firmware that was recently released. According to a recent tweet from hardware leaker chi11eddog, AGESA 1.0.0.4 (SMU 84.79.204) will disable cores on some Ryzen 5 7600X processors, resulting in decreased performance. MSI and ASRock have already removed the firmware from their website, it’s said.
From a chi11eddog tweet:
MSI & ASRock removed X670/B650 AGESA 1.0.0.4 (SMU 84.79.204) BIOS from the websites.
It’s rumored some 7600X are downcore from 2-CCD SKU with Core0 disabled, with which 1.0.0.4 can’t boot. AGESA 1003 is fine.
New SMU 84.79.210 will fix. 1.0.0.4 BIOS still on Gigabyte website.
